Solution: Erect appropriate fencing around the garden perimeter.
Explanation: Fencing is the most reliable deterrent. For rabbits, use chicken wire or hardware cloth at least 2 feet high, buried 6 inches deep or bent outwards at ground level to prevent digging under. For deer, fences need to be 7-8 feet tall, or shorter fences angled outwards or doubled. Electric fencing can also be effective if local ordinances allow.
Notes: Most effective long-term solution but involves cost and labor. Fence type must match the target pest.
